Yes, we most certainly do. Too many of us care only about the automatic
aspect of these compact tuners, and we give up really efficient tuner
operation. Tuners have to be really large to be really good. The components
have to be large and the enclosures have to be large.
This is a good point. Many QRP operators assume that a tuner used for QRP can
be small because one doesn't need the power-handling capability of a larger
tuner. However, if a tuner has x db loss, then that loss will reduce the
strength of a received signal by x db whether the signal is transmitted at 5 or
500 watts!
So if I were building a QRP-only tuner, I would use a big silver-plated inductor
in a big box (although the capacitors could be smaller, since the voltage
requirement would be less).
